Re: A86: Interrupt link handler


yes, this does sound suspiciously familiar. :)

i had another thought, though.  in case you had something to send larger
than the allocated buffer, you could have a couple of pointers to set up.
 set one pointer to the beginning of the data to send and one at the end,
then set a flag and wait.  of course, that's only if you need to send a
LOT of data.  this would also give the ability to send and check a
checksum automatically.

as for syncing, that's just a matter of the protocol used to transfer the
data.  this would be easier to solve using an interrupt because you're
not holding up the rest of the program while waiting for the link port.
